Why succession planning is a practice opportunity

Many small business owners put off thinking about their exit. They're focused on day-to-day operations and assume they'll deal with succession "when the time comes." That's where you come in.

As their accountant or bookkeeper, you're already close to the numbers and understand the business inside out. You're well placed to open the conversation about what happens next, whether that's a sale, a family transfer, or a wind-down. Raising the topic early builds trust and positions your practice as a source of strategic advice, not just compliance work.

Succession planning also creates a recurring advisory engagement. You can support clients across valuation, tax planning, financial preparation, and post-sale transition, and it fits naturally alongside advisory services you may already offer. It's a service that deepens your relationship and increases the value you deliver over time. If you're looking to expand your advisory role, succession planning is a natural starting point.

Types of business succession routes

When you start the succession conversation with a client, it helps to outline the main options available. Each route has different implications for tax, timeline, and the client's ongoing involvement.

Here are the most common succession routes to discuss with your clients:

• Sale to a third party. This involves selling the business to an external buyer, such as a competitor, private equity firm, or individual entrepreneur. It typically offers the highest sale price but requires the most preparation.
• Family transfer. Passing the business to a family member keeps it within the family but needs careful planning around valuation, tax reliefs, and whether the successor is ready to take over.
• Management buyout (MBO). Selling to existing managers or employees can be a smooth transition because they already know the business. Funding the purchase is often the biggest hurdle.
• Wind-down. If no buyer or successor is identified, the business may need to be wound down in an orderly way. This involves settling debts, selling assets, and managing the closure process.

Your role is to help clients weigh up each option against their personal goals, financial position, and timeline. Most clients won't have considered all of these, so presenting the full picture is valuable in itself.

Forming an exit strategy

The best exits are planned, not rushed. Encourage your clients to start thinking about succession three to five years before they want to step away. That lead time is important for getting financials in order, maximising value, and handling the emotional side of letting go.

Leaving a business you've built is personal. Your clients may feel conflicted about stepping back, especially if the business is tied to their identity. Acknowledging that early in the process helps you build a more realistic plan together.

Here are the key areas to cover when forming an exit strategy with a client:

• Identify the most likely succession route and potential buyers or successors.
• Set a target timeline with milestones for financial, legal, and operational readiness.
• Agree on what "exit" looks like, including any transition period, ongoing involvement, or consulting role.
• Review the business structure to ensure it supports the chosen succession route.
• Start early conversations with legal and tax advisors to align on the approach.

Having a written exit plan gives both you and your client a shared reference point. It also makes it easier to track progress and adjust the strategy as circumstances change.

Tax planning for business succession in Ireland

Tax is one of the biggest factors in any business succession. Getting it right can make a significant difference to what your client walks away with. Here are the key reliefs to be aware of when advising clients in Ireland.

CGT retirement relief

Under Sections 598 and 599 of the Taxes Consolidation Act (TCA) 1997, individuals aged 55 or over may qualify for CGT retirement relief when disposing of qualifying business assets. The relief thresholds depend on the individual's age at the time of disposal:

• For individuals aged 55 to 69, full relief may apply where the aggregate consideration for qualifying disposals doesn't exceed the relevant threshold.
• For disposals made on or after 1 January 2025 by individuals aged 70 or over, a reduced threshold applies.

Different rules apply depending on whether the disposal is to a child (Section 598) or to a third party (Section 599). The conditions are detailed and your clients should work with a specialist tax advisor to confirm eligibility.

Capital Acquisitions Tax business property relief

Where a business is being transferred as a gift or inheritance, CAT business property relief may reduce the taxable value of qualifying business assets by 90%, subject to conditions. The disponer must have owned the property for a minimum period before the transfer, and the recipient must retain the assets for at least six years.

This relief can work alongside the group thresholds to significantly reduce or eliminate the CAT liability on a family business transfer. However, eligibility depends on meeting specific ownership and retention conditions.

Your role here isn't to give specialist tax advice, but to flag these reliefs early and connect your client with the right professionals. Starting the conversation well before the planned exit gives everyone time to structure the transaction properly.

Getting the business ready for sale

A business that's well prepared for sale is easier to value, faster to sell, and more attractive to buyers. As the accountant or bookkeeper, you're central to this process.

Clean up the financial records

Buyers and their advisors will scrutinise at least two to three years of financial data during due diligence. Make sure your client's accounts are accurate, up to date, and clearly presented. Reconcile all bank accounts, resolve outstanding items, and ensure management accounts align with filed returns.

If your client isn't already using cloud accounting software, now is the time to migrate. Having real-time, accessible financial data speeds up the due diligence process and gives buyers confidence in the numbers.

Get a business valuation

Your client needs a realistic view of what the business is worth. Valuations can be based on earnings multiples, asset values, or discounted cash flow, depending on the type of business. An independent valuation gives your client a stronger negotiating position and helps set realistic expectations.

Systematise workflows and operations

A business that relies heavily on the owner is harder to sell. Help your client document key processes, delegate responsibilities, and build a management team that can operate without them. The more systematised the business, the more transferable it becomes.

This is also a good time to review the technology stack. Integrated, cloud-based systems show buyers that the business runs efficiently and that the financial data is reliable.

Selling the business

Once the business is ready, the sale process itself has several stages. Your client will need support at each step, and you can either provide that directly or coordinate with other professionals.

Appoint a business broker or advisor

For most small business sales, a broker can help find buyers, manage enquiries, and negotiate terms. Brokers typically charge a percentage of the sale price. Your client should interview several and check their track record with similar businesses.

Manage the due diligence process

The buyer's team will want access to financial statements, tax returns, contracts, employee records, and operational data. Having this organised in advance, ideally in a secure digital format, saves time and reduces the risk of delays.

This is where clean financial records pay off. If the books are accurate and easy to navigate, due diligence moves faster and fewer issues arise.

Handle legal documentation

The sale will involve a heads of terms document, a sale and purchase agreement, and various warranties and indemnities. Your client needs a solicitor experienced in business sales to handle this. As their accountant, you can support by reviewing the financial representations and ensuring the numbers in the agreement match the records.

Plan the post-sale transition

Most buyers will want the seller to stay involved for a handover period, typically three to six months. Help your client plan for this, including what knowledge needs to be transferred, which client relationships need introductions, and how the financial systems will be handed over.

Streamline your practice with Xero

FAQs on small business succession planning

Here are some frequently asked questions about small business succession planning that may come up in client conversations.

When should a client start planning for business succession?

Ideally, three to five years before they want to exit. This gives enough time to optimise the business structure, clean up financials, and explore the best succession route. Starting early also allows time to address any issues that could reduce the sale price.

What's the difference between Section 598 and Section 599 retirement relief?

Section 598 applies to disposals of qualifying business assets to a child, including certain foster children and nephews or nieces. Section 599 covers disposals to third parties. Both require the individual to be aged 55 or over, but the conditions and thresholds differ. Clients should get specialist tax advice to confirm which section applies.

How can you help clients who don't have a successor in mind?

Start by reviewing the succession routes available: third-party sale, management buyout, or wind-down. A business broker can help identify potential buyers. In the meantime, focus on getting the business ready for sale so your client has options when the right opportunity comes along.

What financial records do buyers typically review during due diligence?

Buyers usually want to see at least two to three years of financial statements, tax returns, bank statements, debtor and creditor reports, contracts, and employee records. Having these organised and accessible in a cloud accounting system speeds up the process significantly.

Does CAT business property relief apply to all business transfers?

Not automatically. The relief applies to qualifying business assets transferred by gift or inheritance, subject to conditions around ownership period and retention. The disponer must have owned the assets for a minimum period, and the recipient must retain them for at least six years. Verify eligibility with a tax advisor before relying on this relief.
